First off I am NOT looking for ANY other model besides the X17! No X18, X19, X22, X7, etc. The X17 was the largest pocketbike ever made... it dwarfed the 49cc bikes and was still bigger than the X18 and such. It has a 110cc engine with a 4spd gearbox, 13" rear tire, 12" front tire, etc. They didn't make them long as they were too expensive and they came out with the smaller cheaper ones. I'm looking for them in ANY condition or parts from them. Here's some pics of them. Let me know!
